GM says the new pistons and rings will solve the oil consumption. it will take another 60,000 miles to prove them correct, or not. if they are wrong then am I just out of my $50,000 for the truck, or are their covered warranty repairs warrantied for life?? that is how it should be. my engine has an energy saving feature where 4 cylinders drop out when cruising without torque. but pistons still go up and down. Vacuum above piston 'sucks' oil past rings and is burnt. Causing engine to run itself outa oil. THAT reality did not get changed, so it is still happening. GM says new rings and pistons are different and problems is cured.!?
HOW? engine switches between 4 and 8 cylinders many times each minute. this energy feature is a disaster, avoid it at all costs. GM came up with it to get around some stupid epa rule on fleet mileage. tied to carbon emissions, cow farts, global freeze your ass off warming, and alan gore inventing the internet.
Could GM build a better truck if the epa shut up and shut down? worth a try.
